Answer:
x=9
Step-by-step explanation:
3.5x - 11 = 20.5
Add 11 to each side
3.5x - 11+11 = 20.5+11
3.5x = 31.5
Divide each side by 3.5x
3.5x/3.5 = 31.5/3.5
x =9
Since there is a negative correlation, evident by the negative slope of the equation of the line given to be -0.5, if we take t as 0, we get an equation of,
s = 3.6
This means that if a student does not watch television, he or she spends a maximum of 3.6 hours studying.
Answer:
Bill has $21.
Step-by-step explanation:
There's $135. 84/4=21. At the same time, 21+9=30. 30+21+84=135.
Given:
One linear function represented by the table.
Another linear function represented by the graph.
To find:
The greater unit rate and greater y-intercept.
Solution:
Formula for slope (unit rate):

From the given table it is clear that the linear function passes through (0,5) and (5,15). The function intersect the y-axis at (0,15), so the y-intercept is 15.



So, the unit rate of first function is 2.
From the given graph it is clear that the linear function passes through (0,6) and (-4,0). The function intersect the y-axis at (0,6), so the y-intercept is 6.



So, the unit rate of first function is
.
Now,


And,

Therefore, the greater unit rate of the two functions is 2. The greater y-intercept of the two functions is 15.
18.9 rounded is 19
5.2 rounded is 5
19 * 5 = 95
